Ocular manifestations of internal carotid artery insufficiency

Abstract

8 cases of internal carotid artery insufficiency were studied to find out the various ophthalmic manifestations in such cases. 50% cases had ophthalmic signs and symptoms. These manifestations were amaurosis fugax, central retinal artery block, field defects, pupillary abnormalities and disc oedema. Ammaurosis fugax is a sign of impending carotid insufficiency and these cases must be investigated thoroughly.
